		+
		+	ROCK Pi 4 has one USB OTG port, which can be configured as USB devices with the Linux USB gadget driver, supporting multiple functions as a USB device such as Massive Storage Device and USB networking. We describe how to configure USBNET with a HOST PC.
		+
		+	=== Requirements ===
		+
		+	* ROCK Pi 4
		+	* USB 3.0 or 2.0 male type A to male type A cable
		+	* Host PC running Linux OS
		+
		+	=== Kernel version ===
		+
		+	USB gadget driver must be enabled to configure usb net. kernel should be newer than [https://github.com/radxa/kernel/commit/5e70f1495c248cf6ffa62d974ada7fc2172912cd 5e70f1495c248cf6ffa62d974ada7fc2172912cd].
		+	For Debian Stretch or Ubuntu, you can install the latest kernel from [http://apt.radxa.com apt.radxa.com]. For how to setup Radxa Apt, refer [[rockpi4/radxa-apt]].
		+
		+	=== Load kernel module===
		+	* insert kernel module
		+	On ROCK Pi 4
		+
		+	sudo modprobe g_ether
		+	sudo ifconfig usb0 up
		+
		+	Now you should have usb0 on ROCK Pi 4 enabled.
		+
		+	* Connect the ROCK Pi 4 to PC with the USB A to A cable, make sure the OTG switch is turned at the '''device''' side.
		+	On the host PC ubuntu 16.04, the '''dmesg''' gives something like below:
